She was reincarnated in a reverse harem as... the best friend of the heroine. In a cliche universe where she want to get out as fast as possible, she will have to stay at the heroine's side as the heroine get seduced by the other male characters. This love that they bring to her, is it really so wonderful? Is the heroine herself really a problem? Being the heroine of a isekai... isn't as enviable than you would think.
